CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 623,694, dated April 25, 1899.

Application filed September 19, 1898. Serial No. 691,377. (No model.)

To a whom it may cmwcrn:

Be it known that I, JOHN ANDERSON, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Car- Trucks, of which the following is a full, clear,

- and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in car-trucks; and it consists in the novel combination and arrangement of parts, as will be hereinafter more particularly described, and pointed out in the claims.

In the drawings, Figure l is a combined side elevation and sectional view of my complete invention; and Fig. 2 is a top plan view of the same, showing one side of the truck.

The object of my invention is to construct a car-truck more especially adapted for the electric motor which forms the subject-matter of another application, and embodies in its construction simplicity, durability, and the necessary yielding effect designed for a practical car-truck.

Briefly stated, the invention consists of side members properly secured together by braces and adapted to contain the axle-boxes which form the bearings for the opposite ends of the axles of the track-wheels; cups or boxes forming a continuation of said bearings; a central pedestal; a plate forming the bottom of the same and having a U-shaped depending extension which cooperates with or is located between the intermediate side braces of the truck and operates as a guide for the vertical movement of the upper portion of the said truck; a bearing slidingly located within said pedestal and adapted to receive the end of the armature-shaft of the electric motor; a spring interposed between the top of the pedestal and the upper surface of the said bearing, whereby the propelling disk or wheel which is fixed to the armature-shaft is yieldingly held in frictional contact with the tread of the track -wheels; inverted cups adapted to receive or telescoping with the cups forming a continuation of the bearings which receive the ends of the axles of the track-wheels; coiled springs interposed between said bearings and inverted cups, and

ends of the axles 4: of the track-wheels 5.

Forming a continuation of the boxes 3 are cup-shaped extensions 6, upon the bottom of which rest the lower ends of coiled springs 7, the latter being located within said cups, and inverted cups 8, which receive or telescope with the said cup-shaped extensions 6, and the upper ends of the springs yieldingly supporting the upperportion of the truck, of Which'they form a part. i

The upper or movable portion of the truck 9 is composed of a central hollow pedestal l0, closed at its bottom by a plate 11, which is bolted or otherwise secured to the same and forming a continuation of said plate, and depending therefrom is a U-shaped extension 12, which is loosely received between the adjacent central connecting-braces l3 and operates as a guide for the vertical movement of the upper portion of the truck. Slidingly located within the pedestal 10 is a box 14:, which forms a bearing for one end of the armature-shaft 15 of the electric 1notor,and also located within the said pedestal and interposed between the said box and the upper wall thereof is a coiled spring 16, which opcrates to hold the wheel or disk 17 in frictional contact with the tread portions of the track-wheels 5. The inverted cups 8 are rigidly secured to the pedestal 10 by means of angularly-arranged brace-plates 18,as clearly shown in Fig. 1, and upon said pedestal the car-body is adapted to rest and be supported thereby.

The central side braces 13 of the truck are connected by a transverse beam 19, which extends from one side of the truck to the other and which operates to holdthe parts comprising the lower portion of the truck rigidly together.

I do not limit myself to the precise construction and arrangement of parts as herein shown and described, as it is evident that the same may be varied without departing from the nature of my invention.

In carrying out my invention the boxes 3 for the ends of the axles 4 are specially con structed for the present design of truck, and for this reason the bearing-plates 20 are located at the upper opposite corners of the box or at a point where the pressure and wear will be the greatest.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A cartruck comprising suitable side members constituting the lower portion of the truck, boxes carried by said members forming bearings for the opposite ends of axles for the track-wheels, and a central pedestal yieldingly mounted upon the lower portion of the truck upon which the car-bodyis adapted to rest, as and for the purpose described.

2. A car truck comprising suitable side members constituting the lower portion of the truck, boxes carried by said members forming bearings for the opposite ends of the axles for the track-wheels, acentral pedestal upon which the car-body is adapted to rest, braces forming a rigid part of said pedestal and extending on either side of the same, and spring interposed between the said braces and lower portion of the truck whereby the said pedestal is yieldingly mounted upon the said lowerportion of the truck, as and for the purpose described.

8. A car-truck comprising a lower portion, cup-shaped extensions forming a part of the same, a central pedestal yieldingly mounted upon the said lower portion of the truck, inverted cups located on either side of said ped- 4. A car-truck comprising a lower portion, cup-shaped extensions forming a part of the same, a hollow central pedestal, a removable bottom for the same, an extension forming a part of the latter and cooperating with the lower portion of the truck, inverted cups adapted to telescope with the first-named cups and located on either side of the pedestal and forming a rigid part of the same, coiled springs located within said cups, a box slidingly located within said pedestal and adapted to receive the armature-shaft of an electric motor, and a coiled spring located within the said pedestal and interposed between the top of the same and the box contained therein whereby the wheel or disk carried by the said armatu re-shaft is yieldingly held against the track-wheels, as and for the'purpose described.

5. In a car-truck a box forming the bearing of the end of the axle of the track-wheel, and a bearing-plate forming a part of the said box and located at the upper corner of the same, as and for the purpose described.

6. A car-truck comprising a lower portion, boxes carried by the same, cup-shaped extensions forming a part of said boxes, a transverse beam connecting the opposite sides of said lower portion, a central pedestal upon which the car-bodyis supported, a U-shaped extension depending from the bottom ofsaid pedestal and cooperating with the central lower portion of the truck-frame, inverted cups telescoping with the said cup-shaped extensions, coiled springs located within said cups, and angularly-arrangcd braces rigidly connecting the inverted cups to the opposite sides of the pedestal, as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN ANDERSON.
